Title On the bimodal magnetic field distribution of binary pulsars
نویسندگان
چکیده
We combine the idea of movement of magnetic flux tubes in the stellar interiors with the analysis of crustal physics of accreting neutron stars in lowand high-mass X-ray binaries to explain the bimodal magnetic field distribution of binary pulsars. We propose that this distribution may result from different crustal properties of neutron stars with different accretion rates and amounts of accreted matter. In addition, we may provide an explanation for why the magnetic field strengths of millisecond pulsars with low-mass companions saturate at 13 3 10 G when accreted mass exceeds 10.5 MJ. Subject headings: dense matter—magnetic fields— pulsars: general — stars: neutron

An Explanation for the Bimodal Duration Distribution of Gamma-Ray Bursts: Millisecond Pulsars from Accretion-Induced Collapse
Cosmological gamma-ray bursts (GRBs) could be driven by dissipation of pure electromagnetic energy (Poynting flux) extracted from rapidly rotating compact objects with strong magnetic fields. One such possibility is a young millisecond pulsar (MSP) formed from accretion-induced collapse (AIC) of a white dwarf. The combination of an efficient magnetic dynamo, likely operating during the first se...
متن کاملOn the absence of mildly recycled radio pulsars amongst the population of ordinary single radio pulsars
Current scenarios for the evolution of binaries predict that only 1%or less of the single radio pulsars in the galactic disk have been recycled in a binary. The fraction of such pulsars amongst the detected single radio pulsars is smaller than this. For magnetic field strengths B > 1012 G the period vs. magnetic field diagram shows no evidence for injection of pulsars at P ∼ 0.5 s. For magnetic...
متن کاملOptical Identification of Binary Pulsars: Implications for Magnetic Field Decay in Neutron Stars1
We report the discovery of the optical counterparts of two binary pulsar systems-0655+64 and 0820+02. In accordance with stellar evolution scenarios we find the optical counterparts to be white dwarfs. The existence of a cool and therefore old white dwarf in the 0655 + 64 system contradicts the standard hypothesis of exponential decay of magnetic fields in neutron stars. We resolve this contrad...
متن کاملEffect of Magnetic Field on the Liquid-liquid Equilibria of (Water + Acetic Acid + Organic Solvent) Ternary Systems
The effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 K under atmospheric pressure was investigated. The results obtained show that the strength of the magnetic field (0.02 T) affects the solubility of acetic acid in the used organic solvents. Distribution coefficients and...
متن کاملMagnetospheric interactions of binary pulsars as a model for gamma-ray bursts
I consider a model of GRBs where they arise right before the merging of binary pulsars. Binary pulsars moving through the companion’s magnetic field experience a large, motional electric field ~ E = ~v ∧ ~ B/c, which leads to the release in the pulsar magnetosphere of a pair cascade, and the acceleration of a wind of pure pairs. The energy and energy deposition rate of the wind are those of γ–r...
